This question already has an answer here:

Is there any similar function or plugins for QGIS as in ARCMAP for polygons called autocomplete polygon or autocomplete freehand. I am digitising polygons on a DEM as geomorphological research. I need to digitise polygons next to each other with 0 overlap.

I'm a searching for this function in QGIS 3.4.9-Madeira on a Mac.

    can you explain more what those functions do for those of us who don't use ArcMap – Ian Turton Jul 25 at 10:22

Yes you can, by activating the Avoid intersection in the Snapping options menu (found under Project).

Then just make a new polygon as shown in the left figure with red color. The result will be the yellow polygon in the right figure: enter image description here
